Hickey 3 Abstract The isolation and separation of infected individuals in response to epidemics has persevered throughout history as an effective public health measure. Since the devastation of the Black Death during the fourteenth century, major European cities continued to institute various forms of quarantine in order to address the threat of plague. Following the Great Plague of London in 1665-66 – the last major outbreak of bubonic plague to occur in England – the country had no way of knowing it would never again be visited by the disease in its epidemic form. In the eighteenth century, Parliament took measures aimed at preventing outbreaks of infection from abroad – primarily, through the institution of a rigorous maritime quarantine system. This decision ultimately came about as a result of the standard medical rhetoric of the age, that plague in its epidemic form was much easier to prevent than it was to control. Theories of contagion advanced by English physician Dr. Richard Mead (1673-1754), on which the government’s activity was largely based, were received with dissatisfied medical and communal responses. Yet quarantine, even in its contemporary form, in no way remains free of controversy. In the case of plague, effective preventative measures could not be entirely understood until the epidemiology of the disease had been fully worked out. This essay examines the impact of eighteenth century medical discourse and theories of contagion asserted specifically by Dr. Mead in shaping maritime quarantine protocol in England. Hickey 4 Introduction Following London’s Great Plague in 1665-66, the recession of epidemic plague in the United Kingdom had arrived. Despite a continued appearance of the disease throughout the continent of Europe, and an overall absence of a uniform maritime quarantine policy for roughly forty years following the last pestilential sweep, England managed to evade a widespread outbreak of the contagion indefinitely. However, in response to outbreaks of plague in the Mediterranean during the eighteenth century, Parliament enacted a rigid seafaring isolation system for receiving foreign trade – the recent nonexistence of widespread plague in England not withstanding. After nearly half a century of plague’s cessation in the country at the closure of London’s Great Plague, and quarantine’s previously failed attempts at successfully preventing the introduction of an epidemic in the port city of Yarmouth in 1636, England decided to enforce its first uniform quarantine policy in 1710 . These policies grew increasingly more stringent throughout the eighteenth century, despite a lack of plague ever reentering the Kingdom of Great Britain. Prior to the seventeenth century, England lacked a consistent technique for regulating contact with foreign seaports.1 It was not until 1629 that Parliament made an attempt to initiate an orderly system in response to the Italian Plague of 1629-31, and again during a subsequent outbreak of the pestilence in France and the Low Countries in 1635. 2 Unlike the previously impromptu quarantine measures implemented in England during the sixteenth century, the Privy Council now ordered customs officials to decline or isolate infected ships upon their arrival, yet these methods failed to prevent an epidemic of plague from erupting in England the following 1 Paul Slack, The Impact of Plague in Tudor and Stuart England . (London: Routledge & Kegan Paul, 1985), 221. 2 Ibid. Hickey 5 year.3 In 1655, a surge of plague in the Netherlands prompted Parliament to reestablish these quarantine measures yet again. But after nearly a decade without any reliable trace of the pestilence, the infamous Great Plague of London — the last major outbreak of bubonic plague to occur in the United Kingdom — first struck the district of St. Giles in 1665 and went on to kill an estimated 100,000 people, about 15% of London’s population. 4 Owing to modern science, the etiology of bubonic plague is known to stem from Yersinia pestis , a highly infectious bacterium transmitted from rodents — specifically, the black (Rattus rattus ) or prairie dogs ( Cynomys ) —to other animals, primarily by way of infected Oriental rat fleas (Xenopsylla cheopis ).5 Infected fleas leave the bodies of rodents that have been killed by the bubonic plague bacteria, and in desperate need of a new host, may bite and infect humans. This indirect method of transmission is known to be the most common between rodents and humans, although, humans may also subsequently become infective to other people.6 However, given the absence of this knowledge during the eighteenth century, government measures taken in England to control the spread of plague were primarily aimed at the prevention of human-to- human transmission. 7 In addition, no endemic instances of plague in Britain had been known, and thus, it was inferred that the infection had to have been imported whenever an epidemic occurred. After an outbreak subsided, plague needed to be reintroduced from abroad and British ports in particular – such as London and Yarmouth – played a significant role in facilitating that process. 8 Therefore, the prevention of ships and merchandise being imported from aboard, especially from other infected cities or countries, became an immediate aim of the English 3 Ibid. 4 Lloyd Moote & Dorothy C.

The decision to initiate a systematic method for the detention of these ships arriving from infected areas stemmed from the medical opinion that it was easier to enforce quarantine measures than it was to control plague once it progressed into an epidemic. 9 Therefore, in response to a rise of plague infection in the Baltic Sea region during the Great Northern War (1700-1721), the English government opted to react promptly by implementing the Quarantine Act of 1710 – the first systematic approach aimed at preventing the introduction of plague from abroad – more specifically, by way of infected ships or vessels. Methodology The focus of this paper will be to examine the impact of maritime quarantine practices on eighteenth century English law, particularly in the context of early modern theories of contagiousness, which not only influenced government protocol, but also initiated a genre of medical texts that began to question the capability of empirical evidence to effectively determine the appropriate preventative measures against infectious diseases such as plague. Furthermore, this paper will aim to uncover the ways in which one physician in particular – Dr. Richard Mead (1673-1754) – directly influenced quarantine law through the publication of his treatise, A Short Discourse Concerning Pestilential Contagion, and the Method to be used to prevent it (1720) . Throughout this essay, I will examine an array of eighteenth century medical tracts that coincide with the establishment of Great Britain’s first standardized maritime quarantine system, as well as those that challenged Dr. Mead’s arguments with regard to disease transmission and the role of commerce in spreading plague. In addition to these discourses, this paper will also incorporate 9 Ibid.
